ISPConfig 2: External mailserver setting does not work
Problem: I have set the website to external mailserver in ISPConfig but emails get still delivered to the local server.
Solution: Set all co-domains of this website to external mailserver too. You find the external mailserver setting on the options tab of every co-domain.
Postfix: “queue file write error”
If you get an error like:
Aug 21 12:41:03 webb4 postfix/sendmail[11234]: fatal: web1_user(12967): queue file write error
in your mail log, then the vale for message_size_limit in postfix main.cf is too low. Edit postfix main.cf:
vi /etc/postfix/main.cf
and set the message size limit to a higher value. E.g.
mesage_size_limit = 900000000
and restart postfix:
/etc/init.d/postfix restart
If there is no message_size_limit set in main.cf, just add the line.

How to renew SSL certificates for courier pop3 and imap server on Debian or Ubuntu?
This articles describes the renewal of SSL certificates for courier pop3 and imap server. This is nescessary e.g. when the certificates are expired or contain the wrong hostname.
First delete the exsiting certificates:
rm -f /etc/courier/imapd.pem
rm -f /etc/courier/pop3d.pem
Then edit the template that contains the details for the ecrtificates so that the hostname in the certificate matches the hsotanme of your server and that the email address matches your postmaster email address:
vi /etc/courier/imapd.cnf
vi /etc/courier/pop3d.cnf
and create the new certificates:
mkimapdcert
mkpop3dcert
Courier pop3 and imap have to be restarted so they pick up the new ecrtificates:
/etc/init.d/courier-imap-ssl restart
/etc/init.d/courier-pop-ssl restart
Postfix: One of the users on the system has a CatchAll-email address. He receives all emails, even those intended for users of another site on the same server.
Please check if the domain of the users that receives all emails is the same as the domain $mydomain in /etc/postfix/main.cf. If this is the case, change $mydomain and run
postfix reload
on the shell.
You should never enter a domain that is used for a virtual site on the server as $mydomain in /etc/postfix/main.cf!
